SIP session timer enabled

• The phone supports the SIP draft ietf-sip-session-timer-08. For detailed
information relating to this draft please see http://www.ietf.org.
Session timers provide a basic keep-alive mechanism between 2 user
agents or phones. This mechanism can be useful to the endpoints con-
cerned or for stateful proxies to determine that a session is still alive.
This is achieved by the phone sending periodic re-INVITEs to keep the
session alive. The interval for the re-INVITEs is determined through a
negotiation mechanism defined in the above draft. If a re-INVITE is not
received before the interval passes, the session is considered termi-
nated. Both phones are supposed to terminate the call, and stateful
proxies can remove any state for the call.
• This feature is sufficiently backward compatible such that only one end
of a call need understand the draft and implement the SIP extensions
for it to work.
• Default value: Off.
This is because some server environments support their own mecha-
nism for auditing the health of a session (e.g. Broadsoft).
